Updates in hr min s Forecast update imminent
Alright, let’s break down the Jaconé forecast over the next couple of weeks. The water’s running about 74°F, pretty normal for the time of year. The first few days are small and weedy.
Friday morning, July 3rd is clear and dead calm, with a 2ft SSW swell at 9 seconds. Energy is weak (158). It’s surfable, but nothing to write home about. That afternoon goes onshore at 12 mph.
Saturday, July 4th – size picks up to 5ft from the SSW, period 10 seconds, but it’s cross-shore and messy. Energy now moderate (1019). Afternoon stays cross-onshore, 6ft and bumpy.
Sunday, July 5th – 8ft the morning, 8ft in the afternoon from the SSW at 12 seconds. That’s a proper groundswell, but winds are onshore or cross-onshore all day. Wave energy is strong, around 1517 to 1577. This is expert territory – too big and raw for most. Kite conditions more than paddle surf.
A gap in quality follows, until we hit Monday, July 6th – morning is clean with 6ft S swell at 11 seconds, light cross-offshore breeze. Energy is 961. Afternoon remains clean with a bit more breeze. First good window.
Tuesday, July 7th – morning again is fire: 4ft SSE swell, offshore drift, glassy, 669 energy. Afternoon blown out with 16 mph onshore.
Friday, July 10th – a couple of good sessions: clean 3ft SSW swells at 8-9 seconds, light offshore or cross-off wind.
Saturday, July 11th – 4ft SE groundswell at 12 seconds, clean with offshore wind. Nice.
Sunday, July 12th – morning is a gem: 4ft SE at 12 seconds, glass, complete calm. Energy 501. This is a keeper.
Then things turn ugly through onshore rain and wind from Sunday afternoon through to Monday, July 13th. Skip that.
Tuesday, July 14th – morning is a standout: 5ft swell from the SSE at 11 seconds, 1106 energy, offshore wind, clean. Rated excellent for experienced surfers. You want this.
Wednesday, July 15th – two clean sessions, 4ft from the SSE at 12 seconds. Offshore light winds. Solid.
Thursday, July 16th – afternoon delivers: 8ft from the SSW at 10 seconds, energy 1476, clean with a light cross-offshore wind. Big and powerful – for experts only.
Friday, July 17th – this is the pick of the run. Morning has 7ft from the SSW at 12 seconds, 1248 energy, offshore glass. Afternoon 7ft from the S at 13 seconds, 1352 energy, clean. Both excellent for experienced surfers. Expect crowds.
Saturday, July 18th – a good morning with 6ft from the S at 11 seconds, offshore, 748 energy. The afternoon gets a 4ft, 15-second groundswell but wind picks up to 16 mph cross-off.
The best session of the whole forecast is the morning of Friday, July 17th – big, clean, and powerful. The Tuesday the 14th morning is another perfect window. Call it early for those.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
